try calling Wacom US and describe your problem. Wacom has been great with me over the years. Just send an email to their customer service section.
best of luck, sounds shady
in situations like this, I would personally drive to this guys location and surprise him at work, walking out with whatever I thought was worth my time equivalent (Cintiq for example), no force necessary, explaining directly what you are doing and why, smiling the whole time.
then again, it may not be this black and white. I save an action like that for an extreme case. there may be an issue with your order/shipping, maybe an issue with the credit card, perhaps their building burned down? etc
